Emergency Planet Earth – Part 1

Looming above our precious planet is an unknown number of potential threats that could rain down upon us at any moment. Near earth objects, such as asteroids and comets, continuously swing by us without posing a threat. However, some do come close enough to easily slip into Earth’s gravity. We may have little to no warning before impact. The tracking of newly discovered asteroids and comets confirms that a major collision is only a matter of time.
